City of Hope scientists develop targeted chemotherapy able to kill all solid tumors in preclinical research

On August 1, 2023 Researchers at City of Hope, one of the largest cancer research and treatment organizations in the United States, reported a new study explaining how they took a protein once thought to be too challenging for targeted therapy, proliferating cell nuclear antigen (PCNA), and developed a targeted chemotherapy that appears to annihilate all solid tumors in preclinical research (Press release, City of Hope, AUG 1, 2023, View Source [SID1234633607]). As the scientists continue to investigate the foundational mechanisms that make this cancer-stopping pill work in animal models, they note that there is an ongoing Phase 1 clinical trial testing the City of Hope-developed therapeutic in humans.

Most targeted therapies focus on a single pathway, which enables wily cancer to mutate and eventually become resistant, said Linda Malkas, Ph.D., professor in City of Hope’s Department of Molecular Diagnostics and Experimental Therapeutics and the M.T. & B.A. Ahmadinia Professor in Molecular Oncology. However, the cancer-killing pill Malkas has been developing over the past two decades, AOH1996, targets a cancerous variant of PCNA, a protein that in its mutated form is critical in DNA replication and repair of all expanding tumors.

"PCNA is like a major airline terminal hub containing multiple plane gates. Data suggests PCNA is uniquely altered in cancer cells, and this fact allowed us to design a drug that targeted only the form of PCNA in cancer cells. Our cancer-killing pill is like a snowstorm that closes a key airline hub, shutting down all flights in and out only in planes carrying cancer cells," said Malkas, senior author of the new study published in Cell Chemical Biology today. "Results have been promising. AOH1996 can suppress tumor growth as a monotherapy or combination treatment in cell and animal models without resulting in toxicity. The investigational chemotherapeutic is currently in a Phase 1 clinical trial in humans at City of Hope."

AOH1996 has been effective in preclinical research treating cells derived from breast, prostate, brain, ovarian, cervical, skin and lung cancers and is exclusively licensed by City of Hope to RLL, LLC, a biotechnology company that Malkas co-founded and holds financial interest in.

The researchers tested AOH1996, a small molecule PCNA inhibitor, in more than 70 cancer cell lines and several normal control cells. They found that AOH1996 selectively kills cancer cells by disrupting the normal cell reproductive cycle. It targets something called transcription replication conflicts, which occur when mechanisms responsible for gene expression and genome duplication collide. The investigational therapy prevented cells with damaged DNA from dividing in G2/M phase and from making a copy of faulty DNA in S phase. As a result, AOH1996 caused cancer cell death (apoptosis), but it did not interrupt the reproductive cycle of healthy stem cells.

"No one has ever targeted PCNA as a therapeutic because it was viewed as ‘undruggable,’ but clearly City of Hope was able to develop an investigational medicine for a challenging protein target," said Long Gu, Ph.D., lead author of the study and an associate research professor in the Department of Molecular Diagnostics and Experimental Therapeutics at Beckman Research Institute of City of Hope. "We discovered that PCNA is one of the potential causes of increased nucleic acid replication errors in cancer cells. Now that we know the problem area and can inhibit it, we will dig deeper to understand the process to develop more personalized, targeted cancer medicines."

Interestingly, experiments showed that the investigational pill made cancer cells more susceptible to chemical agents that cause DNA or chromosome damage, such as the chemotherapy drug cisplatin, hinting that AOH1996 could become a useful tool in combination therapies as well as for the development of new chemotherapeutics.

"City of Hope has world leaders in cancer research. They also have the infrastructure to drive translational drug discovery from the laboratory into the clinic for patients in need," said Daniel Von Hoff, M.D., study co-author and a distinguished professor at Translational Genomics Research Institute, part of City of Hope.

City of Hope’s groundbreaking translational research history includes developing the technology underlying synthetic human insulin, a breakthrough in diabetes management, and monoclonal antibodies, which are integral to widely used, lifesaving cancer drugs, such as trastuzumab, rituximab and cetuximab.

As a next step, the researchers will look to better understand the mechanism of action to further improve the ongoing clinical trial in humans. Individuals interested in the Phase 1 clinical trial should review the eligibility requirements at clinicaltrials.gov. If eligible, call 626-218-1133 or visit City of Hope’s clinical trials webpage.

In May 2023, Immutep requested scientific advice from the EMA regarding future development of efti, and in particular whether further toxicity studies would be required before the Company could seek marketing authorisation for efti in Europe. Based on the available clinical data and acknowledgement that additional studies in animal models are unlikely to provide relevant information, the CHMP advised that further toxicology studies are not needed for a future Marketing Authorisation Application (MAA). Similar advice was received from the US Food and Drug Administration (FDA) as it relates to a potential future Biologics License Application (BLA).

Immutep continues to be encouraged with its constructive interaction with regulatory agencies regarding its expanding late-stage clinical pipeline with efti. As recently reported, Immutep has also received positive feedback from the FDA regarding the upcoming TACTI-004 Phase III trial in 1st line non-small cell lung cancer as well as for the AIPAC-003 Phase II/III trial in metastatic breast cancer, which began dosing patients during the second quarter of CY2023.

About Scientific Advice

Scientific Advice is a procedure offered by the EMA to medicine developers for clarification of questions arising during development of medicinal products. The EMA provides scientific advice to support the timely and sound development of high-quality, effective and safe medicines, for the benefit of patients. Scientific Advice is prospective in nature and focuses on development strategies rather than pre-evaluation of data to support a Marketing Authorisation Application (MAA). Scientific Advice is legally nonbinding and is based on the current scientific knowledge, which may be subject to future changes.

About Eftilagimod Alpha (Efti)

Efti is Immutep’s proprietary soluble LAG-3 protein and MHC Class II agonist that stimulates both innate and adaptive immunity for the treatment of cancer. As a first-in-class antigen presenting cell (APC) activator, efti binds to MHC (major histocompatibility complex) Class II molecules on APC leading to activation and proliferation of CD8+ cytotoxic T cells, CD4+ helper T cells, dendritic cells, NK cells, and monocytes. It also upregulates the expression of key biological molecules like IFN-ƴ and CXCL10 that further boost the immune system’s ability to fight cancer.

Efti is under evaluation for a variety of solid tumours including non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), and metastatic breast cancer. Its favourable safety profile enables various combinations, including with anti-PD-[L]1 immunotherapy and/or chemotherapy. Efti has received Fast Track Designation in 1st line HNSCC and in 1st line NSCLC from the United States Food and Drug Administration (FDA).

"The second quarter of 2023 marked another period of strong progress across our business. We are reaching more patients globally with our cystic fibrosis medicines, advancing our late-stage clinical programs and making rapid progress across our research and development pipeline of transformative medicines," said Reshma Kewalramani, M.D., Chief Executive Officer and President of Vertex. "In the second half of the year, we look forward to expanding our leadership in CF; continuing to prepare for several near-term potential launches, starting with exa-cel; and completing major Phase 3 trials including VX-548 in acute pain and the vanzacaftor triple in cystic fibrosis."

Second Quarter 2023 Results
Product revenue increased 14% to $2.49 billion compared to the second quarter of 2022, primarily driven by the strong uptake of TRIKAFTA/KAFTRIO in multiple countries internationally and continued performance of TRIKAFTA in the U.S., including the launch in children with CF 2 to 5 years of age. Net product revenue in the second quarter of 2023 increased 7% to $1.51 billion in the U.S. and increased 26% to $985 million outside the U.S., compared to the second quarter of 2022.
Combined GAAP and Non-GAAP R&D, Acquired IPR&D and SG&A expenses were $1.2 billion and $1.0 billion, respectively, compared to $877 million and $750 million, respectively, in the second quarter of 2022. The increases were due to increased investment in support of multiple programs that have advanced in mid- and late-stage clinical development, increased acquired IPR&D expenses, and the costs to support launches of Vertex’s therapies globally.
GAAP effective tax rate was 21.2% compared to 20.9% for the second quarter of 2022.

Non-GAAP effective tax rate was 21.0% compared to 21.8% for the second quarter of 2022. Please refer to Note 1 for further details on our GAAP to Non-GAAP tax adjustments.
1

GAAP and Non-GAAP net income increased by 13% and 9%, respectively, compared to the second quarter of 2022, primarily driven by strong revenue growth and increased interest income partially offset by increased investment in our mid- and late-stage clinical pipeline, increased acquired IPR&D expenses, and the costs to support launches of Vertex’s therapies globally.
Cash, cash equivalents and total marketable securities as of June 30, 2023 were $12.6 billion, compared to $10.9 billion as of December 31, 2022. The increase was primarily driven by strong revenue growth and operating cash flow, partially offset by our payments to Entrada Therapeutics, CRISPR Therapeutics and other collaboration partners, repurchases of our common stock pursuant to our share repurchase program, and income tax payments.

Full Year 2023 Financial Guidance
Vertex is raising its full year 2023 CF product revenue guidance to $9.7 to $9.8 billion, from $9.55 to $9.7 billion previously. The increase reflects the expected full-year impact of the strong uptake of TRIKAFTA/KAFTRIO in multiple countries internationally and continued performance of TRIKAFTA in the U.S. This guidance includes an approximately 150-basis-point negative impact from changes in foreign currency rates, inclusive of our foreign exchange risk management program. Vertex is also increasing full year 2023 combined GAAP and non-GAAP R&D, Acquired IPR&D and SG&A expense guidance. The increase accounts for higher acquired IPR&D expenses incurred year-to-date, including a $70 million milestone payment to CRISPR Therapeutics.

Vertex’s financial guidance is summarized below:
Current FY 2023 Previous FY 2023
CF product revenues $9.7 to $9.8 billion $9.55 to $9.7 billion
Combined GAAP R&D, Acquired IPR&D and SG&A expenses (2) $4.55 to $4.8 billion $4.35 to $4.6 billion
Combined Non-GAAP R&D, Acquired IPR&D and SG&A expenses (2) $4.1 to $4.2 billion $3.9 to $4.0 billion
Non-GAAP effective tax rate Unchanged 21% to 22%

Key Business Highlights
Cystic Fibrosis (CF) Marketed Products
Vertex anticipates the number of CF patients taking our medicines will continue to grow, including through new approvals and reimbursement for the treatment of younger patients. Recent progress includes:
•Approval from the European Commission for the use of ORKAMBI in children with CF ages 1 to <2 years old who have two copies of the F508del mutation in the CFTR gene. With this approval, approximately 300 children with CF are eligible for the first time for a medicine that can treat the underlying cause of their disease.
•At the European Cystic Fibrosis Society’s (ECFS) European Cystic Fibrosis Conference in June, Vertex presented interim results from the largest real-world study of TRIKAFTA/KAFTRIO, which showed sustained improvement in lung function, reduction in pulmonary exacerbations frequency and lower rates of lung transplant and death for people with CF.
•Approval from the U.S. Food and Drug Administration (FDA) for the use of KALYDECO in children with CF from 1 month to <4 months of age. This approval represents the first and only CFTR modulator approved for this age group. Vertex also submitted Marketing Authorization Applications (MAAs) to the European Medicines Agency (EMA), the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom, and Health Canada for the use of KALYDECO in children with CF from 1 month to <4 months of age.
•Approval from the FDA for the use of TRIKAFTA in children 2 to 5 years of age with at least one F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene or a mutation in the CFTR gene that is responsive to TRIKAFTA. With this approval, approximately 900 children are eligible for TRIKAFTA for the first time. Vertex also completed regulatory submissions with the EMA, the MHRA, Health Canada, and the Therapeutic Goods Administration in Australia for the use of KAFTRIO/TRIKAFTA in children 2 to 5 years of age.

Potential Near-Term Launch Opportunities
Vertex is preparing for the following near-term potential new product launches:

•Exagamglogene autotemcel (exa-cel) in SCD and TDT: Exa-cel is a precise non-viral ex vivo CRISPR gene-editing therapy, which is being developed in collaboration with CRISPR Therapeutics as a potential functional cure for SCD and TDT.
▪The FDA accepted the Biologics License Applications (BLAs) for exa-cel and assigned Prescription Drug User Fee Act (PDUFA) action dates of December 8, 2023, for SCD and March 30, 2024, for TDT. Exa-cel’s BLA for SCD was granted Priority Review by the
3

FDA. The FDA has indicated that they plan to hold an advisory committee meeting for exa-cel. In the U.S., exa-cel has been granted Fast Track, Regenerative Medicine Advanced Therapy (RMAT), Orphan Drug and Rare Pediatric Disease designations.
▪As with the U.S. FDA, reviews of the regulatory filings for exa-cel with the EMA in the EU and the MHRA in the U.K. are well underway. Exa-cel has been granted Priority Medicines (PRIME) and Orphan Drug designation in the EU. In the U.K., exa-cel has been granted an Innovation Passport under the Innovative Licensing and Access Pathway from the MHRA.
▪At the 2023 Annual European Hematology Association (EHA) (Free EHA Whitepaper) Congress in June, Vertex presented positive interim results from the pivotal trials of exa-cel in SCD and TDT as of a September 2022 data cut. Both trials met the primary and key secondary endpoints at pre-specified interim analyses, and the data continue to demonstrate transformative, consistent and durable benefit. The data presented at EHA (Free EHA Whitepaper) were the basis of the EMA and MHRA regulatory filings for exa-cel. Vertex expects to present updated clinical data that served as the basis of the FDA filing at a future medical congress.
▪Dosing in the Phase 1/2/3 CLIMB-111 and CLIMB-121 studies is ongoing, and Vertex continues to enroll and follow patients in the CLIMB-131 long-term follow-up study.

•Vanzacaftor/tezacaftor/deutivacaftor, the next-in-class triple combination, in cystic fibrosis.
▪In the fourth quarter of 2022, Vertex completed enrollment in the pivotal SKYLINE 102 and SKYLINE 103 trials, which evaluate the efficacy and safety of vanzacaftor/tezacaftor/deutivacaftor relative to TRIKAFTA in patients with CF 12 years of age and older. More recently, Vertex also completed enrollment in the RIDGELINE study of vanzacaftor/tezacaftor/deutivacaftor in children with CF 6 to 11 years of age. Vertex expects to complete both the SKYLINE and RIDGELINE studies by the end of 2023 and share the results of these studies in early 2024.

•VX-548 in acute pain: Vertex has discovered multiple selective small molecule inhibitors of NaV1.8 with the objective of creating a new class of pain medicines that have the potential to provide effective pain relief, without the limitations of opioids and other currently available medicines.
▪Vertex continues to enroll the Phase 3 pivotal program, including two randomized controlled trials in abdominoplasty and bunionectomy and a single arm safety and
4

effectiveness trial, for its lead compound, VX-548, for the treatment of moderate to severe acute pain.
▪Vertex expects to complete the pivotal program in late 2023 and share results from these studies in late 2023 or early 2024. In the U.S., VX-548 has been granted Breakthrough Therapy and Fast Track designations for moderate to severe acute pain.

R&D Pipeline
Vertex is delivering on a diversified pipeline of potentially transformative small molecule, mRNA, cell and genetic therapies aimed at serious diseases. Recent and anticipated progress for programs in clinical development is summarized below.

Cystic Fibrosis
Vertex continues to pursue next-in-class, small molecule CFTR modulator therapies, as well as an mRNA therapy for the approximately 5,000 patients who cannot benefit from CFTR modulators alone.
•Vertex is developing VX-522, a CFTR mRNA therapeutic, in collaboration with Moderna. The goal of this therapy is to treat the underlying cause of CF by programming cells in the lungs to produce functional CFTR protein, and it is aimed at the treatment of the approximately 5,000 people with CF who do not produce any CFTR protein. Vertex is enrolling patients in a single ascending dose (SAD) clinical trial for VX-522, and the Company expects to complete the SAD and initiate a multiple ascending dose (MAD) study in 2023. In the U.S., the FDA has granted Fast Track designation to VX-522.
•Consistent with its overall strategy, Vertex takes a portfolio approach to all of its programs and is advancing additional CFTR modulators with the goal of bringing more patients to carrier levels of sweat chloride.

Beta Thalassemia and Sickle Cell Disease
•Two global Phase 3 studies of exa-cel continue to enroll and dose patients 5 to 11 years of age with TDT or SCD.
•Additionally, Vertex continues to work on preclinical assets for gentler conditioning for exa-cel, which could broaden the eligible patient population from 32,000 patients to more than 150,000.

Acute and Neuropathic Pain
•The Phase 2 dose-ranging study of VX-548 in patients with diabetic peripheral neuropathy, a common form of peripheral neuropathic pain, has been fully enrolled.
5

•Dosing in the Phase 2, 12-week VX-548 study continues, and Vertex expects to complete this study in late 2023 and share results in late 2023 or early 2024.
•Consistent with its overall strategy, Vertex takes a portfolio approach to all of its programs and is advancing additional NaV1.8 inhibitors as well as NaV1.7 inhibitors through research and earlier stages of development for pain.

APOL1-Mediated Kidney Disease (AMKD)
Vertex has discovered multiple oral, small molecule inhibitors of APOL1 function, pioneering a new class of medicines that target an underlying genetic driver of kidney disease.
•Vertex continues to enroll and dose patients in the pivotal program for inaxaplin, a single Phase 2/3 clinical trial in patients with AMKD, and expects to complete the Phase 2B dose-ranging portion of the study in 2023.
•Inaxaplin was granted Breakthrough Therapy designation by the FDA for FSGS, as well as Orphan Drug and PRIME designations by the EMA for AMKD.

Type 1 Diabetes (T1D)
Vertex is evaluating cell therapies using stem-cell derived, fully differentiated, insulin-producing islet cells to replace the endogenous insulin-producing islet cells that are destroyed in people with T1D, with the goal of developing a potential functional cure for this disease. Vertex has three programs that use these fully differentiated cells.
1.VX-880, fully differentiated cells with standard immunosuppression: Vertex established proof-of-concept for VX-880 in 2022. In June 2023, Vertex presented positive, updated clinical data from the ongoing VX-880 Phase 1/2 study at the American Diabetes Association Scientific Sessions (ADA). The Phase 1/2 study is designed as a sequential, multi-part clinical trial to evaluate the safety and efficacy of VX-880. In Part A, the first two patients received half the target dose of VX-880 cells. In Part B, patients received the full target dose with staggered dosing. Based on the results from Parts A and B, Vertex has initiated Part C of the study, with concurrent dosing at the full target dose, with trial sites currently active in the U.S., Canada, Norway, Switzerland, the Netherlands and France.
In the data presented at ADA, all patients from Parts A and B of the study treated with VX-880 engrafted islet cells, produced endogenous insulin (C-peptide) and had improved glycemic control while reducing or eliminating insulin use. The two patients with at least one year of follow-up met the criteria for the primary endpoint of elimination of severe hypoglycemic events (SHEs) and HbA1C <7.0 and also achieved insulin independence.

2. VX-264, fully differentiated islet cells encapsulated in immunoprotective device: VX-264 uses the same stem cell-derived, fully differentiated islets used in the VX-880 program, which are encapsulated in a novel device designed to shield the cells from the body’s immune system and obviate the need for immunosuppressive therapy. Vertex is enrolling and dosing patients with VX-264 in a Phase 1/2 clinical trial that is a sequential, multi-part study to evaluate the safety, tolerability and efficacy of VX-264. Part A of the study will dose patients with a partial dose of cells and a stagger between patients, and Part B will dose patients with a full target dose and a stagger between patients before moving to concurrent dosing in Part C. The study is enrolling patients in the U.S., Canada and the Netherlands, with additional global sites to be activated in the coming months. The first patient in Part A has been dosed.

3. Edited fully differentiated cells: Vertex’s hypoimmune cell program involves using CRISPR/Cas9 to gene edit the same stem cell-derived, fully differentiated islets used in the VX-880 and VX-264 programs, in order to cloak the cells from the immune system. This is yet another possible path to eliminate the need for immunosuppressive therapy. This program is progressing through the research stage.

To further expand Vertex’s capabilities in cell therapy manufacturing, in June 2023, Vertex and Lonza announced a strategic agreement to support the manufacture of Vertex’s portfolio of investigational stem cell-derived, fully differentiated insulin-producing islet cell therapy. This agreement will help accelerate the development and commercialization of Vertex’s potentially transformative cell therapy products for T1D.

Alpha-1 Antitrypsin Deficiency
Vertex is working to address the underlying genetic cause of alpha-1 antitrypsin (AAT) deficiency by developing novel small molecule correctors of Z-AAT protein folding, with a goal of increasing the secretion of functional AAT into the blood and addressing both the lung and the liver aspects of AAT deficiency.
•Vertex is enrolling and dosing patients in a 48-week Phase 2 study of VX-864, a first-generation AAT corrector, to assess the impact of longer-term treatment on polymer clearance from the liver, as well as the resultant levels of functional AAT (fAAT) in the plasma. Vertex expects to complete enrollment in this study in 2023.
7

•Additionally, Vertex continues to enroll and dose healthy volunteers with VX-634, a follow-on small molecule AAT corrector. VX-634 is the first in a series of next-wave investigational molecules with significantly improved potency and drug-like properties compared to previous Vertex AAT correctors. Vertex expects to complete enrollment and dosing in this study in 2023.

Muscular Dystrophies
Vertex is also advancing preclinical assets in muscular dystrophies, including Duchenne muscular dystrophy (DMD) and myotonic dystrophy type 1 (DM1).

Investments in External Innovation
As part of the collaboration with CRISPR Therapeutics on hypoimmune cells for T1D, Vertex achieved a research milestone in the second quarter of 2023, resulting in a $70 million milestone payment payable to CRISPR.

Study Published in JNCI Cancer Spectrum Demonstrates Real-World Utility of Veracyte’s Decipher Prostate Genomic Classifier in Prostate Cancer Treatment

On August 1, 2023 Veracyte, Inc. (Nasdaq: VCYT) reported the publication of a large, real-world study reinforcing the Decipher Prostate Genomic Classifier’s ability to guide personalized treatment approaches for men with prostate cancer (Press release, Veracyte, AUG 1, 2023, View Source [SID1234633599]). The study utilized data from the first linkage of prostate cancer cases reported by central cancer registries participating in the Surveillance, Epidemiology, and End Results (SEER) Program, with Decipher test results. SEER is a population-based cancer registry supported by the National Cancer Institute (NCI). The findings appear online in JNCI Cancer Spectrum.

In the U.S., an estimated 288,300 men are expected to be diagnosed with prostate cancer in 2023 and 34,700 men are expected to die from the disease.[1] Treatment for prostate cancer is primarily selected based on clinical risk factors such as Gleason score, clinical stage and prostate-specific antigen (PSA). Clinical factors alone, however, do not always reflect the true biology of the tumor, which can lead to over- or under-treatment of patients with prostate cancer. The Decipher Prostate test molecularly assesses the likelihood of a patient’s cancer metastasizing within the next five years. Armed with this information, a physician can recommend tailored treatment plans, including no treatment, less intensive treatment or earlier, more intensive interventions.

"Validation from multiple randomized trials has consistently demonstrated the prognostic performance of the Decipher 22-gene expression test," said Daniel Spratt, M.D., chair of the Department of Radiation Oncology at UH Cleveland Medical Center. "This study builds upon this with real-world data of how the test is being used in a population sample and demonstrates how we are moving toward the goal of personalized therapy. Patients with a low Decipher score, indicating a better prognosis, can be guided towards treatment de-escalation, and those with higher Decipher scores, indicating a worse prognosis, can be guided towards appropriate treatment."

The study analyzed data from 8,297 patients in the SEER registry who received a primary prostate cancer diagnosis from 2010 to 2018 and underwent Decipher Prostate testing. Researchers evaluated the association between the patients’ Decipher scores (range 0-1) and risk groups (low, intermediate and high), and the use of active surveillance and watchful waiting (AS/WW) as well as adverse pathology at the time of radical prostatectomy (RP).

The results demonstrated that AS/WW was highest among subjects with low-risk Decipher biopsy results (41%), compared to those who had intermediate-risk (27%) or high-risk (11%) scores. Among subjects with clinically low-risk prostate cancer, 65% of those with low-risk Decipher results were managed with AS/WW. Among patients classified as NCCN low or favorable intermediate risk, higher Decipher risk was associated with greater use of local therapy and nearly three times the odds of harboring adverse pathology compared to those with low Decipher risk. The use of prostatectomy and radiotherapy increased with higher Decipher risk groups. For example, prostatectomy was used in 22% of low-, 30% of intermediate-, and 39% of high-risk Decipher patients and radiotherapy was used in 16% of low-, 24% of intermediate-, and 35% of high-risk Decipher patients. The study also found a significant association between higher Decipher risks groups and the use of post-operative radiotherapy.

"This study is further evidence that the Decipher Prostate test provides valuable clinical information to physicians and their patients with prostate cancer. In contemporary practice, physicians treat patients with higher-risk Decipher scores more aggressively, and patients with lower-risk Decipher scores more conservatively," said Elai Davicioni, Ph.D., Veracyte’s medical director for Urology. "This is the first large national database study in ongoing collaborations with the National Cancer Institute SEER program and represents our sustained commitment to research and real-world evidence development."
